Description NBx Minimus apparel uses cutting-edge materials and minimal seaming to achieve intensely lightweight results. The New Balance NBx Minimus Jacket weighs in nearly as light as a feather, despite the fact that it's loaded down with the very best selection of premium features: wind and water resistance, secure pockets, front and back reflectivity, underarm vents, and on top of it all that it's packable into a pocket for convenient storage.
